Joaquin Phoenix on Letterman…kind of.

In anticipation of what appears to be Joaquin Phoenix’s last film, Two Lovers, the actor appeared on Letterman last night – or some sort of shadow of him.
Phoenix appeared totally whacked out, totally hairy and totally bizarre. He confirmed that he’s leaving the business, but when asked why, merely said “uhhh…I dunno”.

…right.

There was also confirmation that Joaquin isn’t going down the route of the Johnny Cash-style music that he did so well in Walk the Line, but rather chasing a hip-hop career.

This is kind of cringe, but awesome at the same time:

So is it some sort of weird advertising campaign, like Crispin Glover’s appearance on Letterman in character, or has he really gone that downhill?
